Bug Description
Release: 9.04
Installed from the LiveCD, worked fine. When then booting from the HD w/o interaction, the PC freezes after the ubuntu progressbar is displayed with a black screen.
If I press CTRL-ALT-F1 as soon as the progress-bar screen appears I can see many error messages from ATA2 similar to:
[ 35.845586] ata2.00: exception Emask 0x2 SAct 0x6de SErr 0x3000400 action 0x6
[ 35.845636] ata2.00: irq_stat 0x45000008
[ 35.845678] ata2: SError: { Proto TrStaTrns UnrecFIS }
[ 35.845737] ata2.00: cmd 60/40:08:
[ 35.845739] res 50/00:07:
along with a timeout message
after some time these meessages stop. I can then press ENTER and {initramfs} shows up. I enter EXIT and then some more progress messages come, then finally the system boots up.
Hardware (as reported by vista):
Acer Timeline 3810T
HD Hitachi HTS545032B9A300
Intel ICH9M-E/M SATA AHCI Controller
I also tried to install 8.10 and 9.04 with http://
DMESG is attached.
switching the SATA mode frm AHCI to IDE prevents the issue overall. I consider this a workaround however and not a solution, since this disables any pre-installed Vista setup.
additionally, booting with "libata.noacpi=1" in the kernel line also resolves the issue
